UFS installs solar plants on all campuses, bolstering renewable energy amid continuing power cuts

Bloemfontein Campus Solar Farm — The solar plant on the UFS’s Bloemfontein Campus, part of the university’s commitment to combatting loadshedding and embracing sustainable energy.

The University of the Free State (UFS) has installed solar plants across its three campuses.

The university says this is in response to the call for urgent solutions to loadshedding and the promotion of environmentally sustainable, cleaner, and renewable energy solutions.

Nicolaas Esterhuysen, Director of Engineering Services at UFS University Estates, said,

“The PV (photovoltaic) systems are grid-tied without storage to ensure maximum benefits and faster payback periods.”

Esterhuysen said the UFS has saved up to R32,5 million since the first solar plant was commissioned in 2017 to help the UFS reduce the impact of loadshedding and its carbon footprint and energy costs. “This will substantially increase this year with the commissioning of two large new ground-mounted solar plants on the Bloemfontein Campus,” he said.

“The microgrid installation on Qwaqwa Campus is one of the biggest solar diesel hybrid systems installed in South Africa. It allows us to keep the campus running despite excessive power interruptions.”

The UFS is currently embarking on research as part of the Grid-related Research Group (GRRP) under the Interdisciplinary Centre for Digital Futures (ICDF) to also help staff and students with understanding renewable energy and sustainability.

Esterhuysen said the plants are further evidence of the UFS’s commitment to renewable and energy saving solutions. “It is our flagship project, but our focus is also on energy saving initiatives – to ensure we are becoming more energy efficient and eliminate energy wastage. We have plans for expansion on all campuses. Some of the highlights are an off-grid solution for the new student centre at Qwaqwa Campus and to make South Campus a self-sustaining campus.”

The installed grid-tied system solar plants are operating without batteries on all three campuses, giving the university an optimal configuration between capital cost and payback period.

The energy generated at the solar plants:

Bloemfontein Campus – 3688 kWp

Qwaqwa Campus – 918 kWp

South Campus – 759 kWp

Paradys – 125 kWp

SmartDrive devices give UFS wheelchair users more independence

Students who make use of wheelchairs at the University of the Free State (UFS) will now be able to move around campus more independently than before. This is thanks to two SmartDrive Power Assist devices acquired by the university.

Accessibility is very important to the institution and with these devices clipping onto a manual wheelchair to make it motorised, students will not have to ask for help that often. It will assist them in overcoming obstacles they face every day.

Different surfaces pose different challenges
According to Martie Miranda, Head of the Center for Universal Access and Disability Support (CUADS), one of the most important advantages of the SmartDrive machines is that it enhances the independence of students. The devices were bought with funds received from the Department of Higher Education and Training specifically allocated for accessibility and infrastructure.

“While the UFS is addressing inaccessibility on its campuses, which will take time, this will help to motorise wheelchairs for wheelchair users to move around more easily. Students can now move around independently without necessarily asking for help, for example, to get up very steep ramps.” Miranda says some surfaces, such as grass and gravel, has its own unique challenges for wheelchair users.

A few years coming
The SmartDrive devices are operated by a Bluetooth watch. By tapping twice on the chair or clapping twice, the motor propels the wheelchair forward and stops when tapped twice, while also braking with one’s hands. The speed can also be controlled by the user. The machines use rechargeable batteries, with a fully charged battery lasting up to 15 hours.

Acquiring the devices was a process of a few years, and CUADS is happy to finally employ them to the benefit of their students. Miranda says the determination and support of Prof Nicky Morgan, Vice-Rector: Operations, and the assistance of Nico Janse van Rensburg, Senior Director: Top Management, were instrumental in buying the devices.
